What happened?

I am oublishing some OPC UA info on a Web Socket.
The Websocket Server stops sending message when the pipeline instantiating it is stopped and restarted even without any modification. I have to redeploy Stream pipe and reimport everything than it works again for the first run of the pipeline instantiating the Web Socket. If I stop/start it again, I have to redeploy again...

How to reproduce?

Instantiate a WS in a pipleline together with an OPC UA Data adapter and a Projection Data Processor to select what data to send to WS.
Run the pipeline
Check it is sending messages with wscat -c ws://xxx.xxx.xxx.xxx:xxx
Stop and start the pipeline and check again with wscat -c ws://xxx.xxx.xxx.xxx:xxx

Expected behavior

It seems that the pipeline is loosing the connection to the WS once stopped
